AUTO TUBE WINDER.

Application fiiea'ri rn 27, 1921. Serial No; 464,838.

To aZZ'w/zom it may concern:

Be it known that FREDERICK CoA'rns, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio, hasinvented certain new and useful Improvements in Auto Tube VVinders, ofwhich the following is a specification;

to whichblanks consisting of rectangular strips of paper may be fedandwhich will be delivered from the machine in the form of tubular canbodies. A second important object of the invention is to provide animproved machine for forming tubular can bodies wherein improved meansis used for rotating a tube;

former at a predetermined point in its travel over a prescribed path.

A third important object of the invention is to provide an improvedmachine of this class having improved stripping means for removing thecan body from-the former.

A fourth important object of the invention is to provide an improvedmachine of this class having an automatically operating intermittentclutch and a Oarrierhead driven from the clutch and carrying the canformer so that, at stated intervals, the rotation of the former isstopped automatically while the winding and stripping operations takeplace. I r

A fifth important object of the invention is the provision of a machineof this class having an improved mechanism for holding the tube or bodyformers against rotation as the body is wound thereon.

A sixth important object of theinvention is the provision, in a machineof this clas's, of novel mechanism for holdmg the glued end of a blankdown on the body of the blank until the same will adhere firmly.

With the above and other objects in view, the invention consists ingeneral of certain novel details of construction and combinations ofparts hereinafter fullydescribed, illustrated in the accompanyingdrawings, and specifically claimed. Inthe accompanying drawings, likecharacters of reference indicate like parts in the several views, and

Figure 9 is a perspective View of one of the pressing devices herewithused;

In the embodiment of the invention herein illustrated there is providedaframe 10. Journalled in this frame is a main shaft 11 which is providedwith a belt pulley 12 or some othersuitable form of drive. this mainshaft is a pinion 13 which meshes with a gear'14 mountedon a shaft 15.At 16 is shown a clutch, the clutch being preferably of the typedisclosed inmy copending application, filed the 27th day ofApril, 1921.and bearing-the Serial Number 464,831. In place of the pins shown insaid copending application this clutch is provided, 011 one of itsmembers 17, with a'series of teeth 18. On a stop shaft 20 is mounted thestop lever 21 of the clutch, this lever having ro tatably mountedthereon aroller 22 in constant engagement with the cam 23 fixed ontheshaft 11. Thusthe rotation of the shaft- 11 1 rotates thegcam 23 'a ndoperates to free the lever '21 from the teeth 18 oneach rotation of saidshaft 11. In the present instance the'rat'iobetween the gears 13 and 14;is intended to be four toone and there are four of the teeth 18 so thatthe clutch 16 is disengaged from the shaft 15 four times a ratio ofmovement rather than diameterv since during the disengagement of theclutch j there will be a pause in the revolution of the shaft 15 it mustbe compensated as otherwise the shafts 11 and15 would not revolve in theproperratio. On the shaft 15 1s mounted a spider or former carrier 24provided with a seriesof bearings 25 wherein are rotatable mountedshafts 26 each carrying a body former 27 of the type described in mycopending application bearing the Serial Number 464,834 and filed the27th day of April 1921. That is to say each of these body formers is ahollow cylinder having a central cavity 28 with lateral ports 29 leadingtherefrom. Carried on the shaft 11 is a gear 30 which meshes with a gear31. EX- tending through a vacuum box 32 is a vacuum pipe 33 whichevolves with the gear 31 and carries on its end a disk 34 provided witha recess wherein is seated a rubber clutch and packing ring 35; Mountedon the shaft 11 is a cam 36' and a lever 37 pivoted at one end, as at38, carriesa cam roller 39 engaging in the groove of the-cam 36. Thislever 37 operates to oscillate once in each revolution of the shaft 11and the cam 36 is provided with a dwell 40 wherethrough the rollerpasses. Moreover the; lever 37 is so connected to the shaft 33 as tomove the latter as the lever oscillates, It will be noted that the lever21 stops-the clutch and disengages the shaft 15 at a time when a formerhead 27 is in alinement with the shaft 33. Also at this time the lever37 has moved to bring the head 34 into engagement with the former'28which is in alinement. Consequently the head 34 acts as a fringe clutchand rotates this former. At the same time the movement of the leveropens a valve 41in a suction pipe 42, the valve being pro vided withoperating handle 43 connected to I the lever 37 by a link 44. At 45 is abearing 1 while one former 27 is revolved by the shaft wherein isslidably mounted a shaft 46 carrying gripper fingers 47. -M0untedslidably on each of the former heads is a stripper 48 having a rib49engageable when in proper position, in grooved portions 50 of saidstripper fingers. This shaft 46 is connected by pins 51 to the lever 37These parts are so arranged and proportioned that during thedisengagement of the main clutch and 33 the lever 37 will oscillate onceto move the stripper 48 overthe former 27 just be-V hindthatformerwhichis alined' with the shaft 33. It will be seen that asuitable feed guide 52-isprovided :atthe properpoint to guide the paper:strip Srto the rotating former; -On-the head 25 are mounted pins 53 andon each of these pinsis provided-'a-sleeve "54 carrying atone end apresser finger'55 7 while at the otherend "each sleeve has an arm 56provided-fat its ends'with spaced prongs 57 and 58 the I prong '58being-closer to the sleeve and'longer than'the prong 57.

i Projecting from each stripper48 is a pin 59.

Onithe shaft 115 is a sleeve-60 in which the shaft freelyrotates and atone end of this sleeve is an arcuate cam 61 having 'atits end i aprojection 62. Extending from each of the arms 56 is a finger 63 whichis so arranged that When the carrier head rotates these fingers 63 arebrought successively into contact with the cam 61 in such manneras tolift the presser 55 away from theformer. From an inspection'of'Figure 3it will be seen that the presser is kept well out of engagement withsuch former and upon arrival at the projection 62 is moved still furtheraway from engagement. In order to accurately time the arrival of thepin59 in position to be engaged between the fingers 57 and 58 there isprovided on the shaft 11 a cam 64 which oscillates a lever 65 projecting from the sleeve 60. .Thus at each revolution of the cam 11, just asa respective finger 63 has rested on to the projection 62 the lever 65will be drawn forward by a spring 66 and the cam 61 slipped from beneathsaid finger 63 allowing the presser ,55 to move toward the former. Thisoperation takes place just as the former has been acted upon 7 stripper.It will be noted that this result is accomplished by aid of the actionof the cams on the shaft 11 as Well as by the action of the cam 61,these cams being in such timed relation that the pin 59 makes nearly acomplete revolution during the time that the presser 55 is held outwardby the lug 62, this lever being released at the proper instant to permitthe pin 59 t'o'drop between the fingers or jaws 57'and 58. r

From the foregoing it will be seen that the blanks are fed successivelyon the'former as they are brought around to position, the former beingrevolved once, the glued. ends of the blanks held down until the stripper stop is reached. At this time the strip-a per operates and theformer is free to ree ceive another blank.- o 7 7 It will be noted thatspringsf67 and' 68" are used to hold the presser and-lever 21 inpositionrespectively; i

It is obvious that minor changes may be,

ventioiiwvithout departing from the matepresser islifted away to permitaction of the rial principles thereof. Itisnot' thereforex desired toconfine the invention to the exact, form herein shown and described, butit is wished to include all such'as properly come within the scopeclaimed.
